   <h2> About ... </h2>
   
     <!--    <div align="left" style="margin-left:50px;margin-right:150px;"> -->
    <p> <em> Emotion Twenty Questions (EMO20Q)</em> is a dialog-based guessing
    game.  It is much like the ordinary twenty questions game, but
    instead of picking an object, player one (the <em>answerer</em>)
    picks an emotion word.  Player two (the <em>questioner</em> )
    then tries to guess the emotion in less than 20 questions. </p>


    <p> This game is meant to be fun, but it will also benefit
    science, technology, and society.  Science, like this game, often
    starts with a good question. Scientifically, we want to study how
    people understand emotions by observing their natural language
    behavior.  For technology, it will help computers understand human
    language that refers to emotions.  For society, it will help
    people "get in touch with" their emotions and learn to express
    these emotions articulately.  To these ends, your chat data will
    be saved securely and studied anonymously. </p>

    <h2> For The Curious ... </h2> 

    <p> The study of computers and emotions is known
    as <a target="_blank"
    href="http://en.wikipedia.org/wiki/Affective_computing">affective
    computing</a>.  At the <a target="_blank"
    href="http://sail.usc.edu">sail lab</a>, we have
    a <a target="_blank" href="http://sail.usc.edu/emotion/"> big
    group that studies emotions</a>.  In
    particular, this project focuses on
    <a target="_blank" href="http://sail.usc.edu/~kazemzad/emotion_in_text_cgi/">emotions in text</a>.
    In contrast to other most other approaches to emotions in text, this does not study the emotion that
    the speaker/writer feels, but rather the emotional meaning that they are trying to convey.  This is 
    useful in cases when the speaker/writer is refering to 2nd hand emotional experiences like gossip or 
    emotional experiences in the past (emotional self-report).  </p>


    <p> The human-human chat site is based on <a target="_blank"
    href="http://en.wikipedia.org/wiki/Extensible_Messaging_and_Presence_Protocol">XMPP/Jabber</a>
    instant messaging technology.  The server runs <a target="_blank"
    href="http://en.wikipedia.org/wiki/Ejabberd">ejabberd</a> and this
    web-client is based on <a target="_blank"
    href="http://www.ijab.im">iJab</a>. XMPP is an open standard, and
    the client and server software are free and open
    source.  Likewise, we endeavor to make our data and methodologies 
    available to the community.  Currently these are hosted at
    <a href='http://code.google.com/p/emotion-twenty-questions/'> code.google.com </a>.  
    <a target="_blank" href='http://sail.usc.edu/~kazemzad/emo20q/acknowledgements.html'>
    Here </a> is a description of how EMO20Q was inspired. </p>

    <p> It is an observed fact that normally developing children ask
    lots of questions when they are in the period of rapidly
    increasing vocabulary.  We feel that we can use this behavior as a
    model for making computers that can learn language.  From a
    theoretical point of view, asking a question can be seen as the
    colloquial equivalent of making a hypothesis.  The logician
    Charles Sanders Peirce identified hypothesis, or abduction, as one
    of the three main forms of reasoning.  The tradition of
    question-asking has a long history that goes back to the Socratic
    Method.  </p>

    <p> The automated agent (computer) player of EMO20Q is powered by
    a graph-based structure that allows us to analyze emotional
    concepts in terms of graph connectivity. This can make for some
    interesting visualizations
    like <a href='http://sail.usc.edu/~kazemzad/emo20q/prefuseDemo/'>
    this animation </a> (warning: can be slow to load). Other graph visualizations can be found
    <a href='http://sail.usc.edu~kazemzad/Sites/share/emo20q_images/'>
    here</a>.  </p>

    <p> Another aspect of understanding EMO20Q is determining
    how people conceptualize answers to yes/no questions, as can be
    seen in <a href='fuzzyYN/t1_shortlist_boxplots_sorted.pdf'>Fuzzy
    Yes/Yo graph 1 </a>
    and <a href='fuzzyYN/t1_longlist_boxplots_sorted.pdf'> Fuzzy
    Yes/No graph 2</a>.  </p>
